<HTML><BODY style="word-wrap: break-word; -khtml-nbsp-mode: space; -khtml-line-break: after-white-space; ">Ok.<DIV><SPAN class="Apple-style-span">I tested with the R.app GUI (R-GUI-Debug) from the web page you mentioned. I used the one under "Built for R 2.2.x" because the one for 2.3.x didn't work with my R and I didn't see an R 2.3 at cran.r-project.org to download. This also crashed when presented with the same problem. I have attached my bug report. <FONT class="Apple-style-span" face="Arial" size="5"><SPAN class="Apple-style-span" style="font-size: 17.2px;"><B></B></SPAN></FONT></SPAN></DIV><DIV><BR class="khtml-block-placeholder"></DIV><BLOCKQUOTE type="cite">quartz.save("plot.pdf",type="pdf")</BLOCKQUOTE>The quartz.save command did save without crashing, but the PDF it produced was of a decidedly odd phenotype with backwards blue writing over a large part of it.
